SEWING-MACHINE PRESSER-FOOT.

SPECIFICATION forming part of Letters Patent No. 722,441, dated March10,1903. Application fil ed September 1, 1899. Serial No. 729,193. (Nomodel.)

To a whom it may concern.-

Be it known that I, RUssEL G. WooDWARD, a citizen of the United States,residing at Waukegan, in the county of Lake, State of Illinois, haveinvented certain new and useful Improvements in Sewing-Machines, ofwhich the following is a description, reference being had to theaccompanying drawings and to the letters and figures of refer- IO encemarked thereon.

My invention relates to an improvement in presser-feet forsewing-machines, and has been designed especially for use on what isknown as the Union Special Yoke Rufliing Sewing Machine, upon which Imade application for Letters Patent of the United States on the th dayof July, 1898, Serial No. 686,444.

It is the object of the present invention to 20 provide a presser-foothaving a part which partakes not only of a tilting movement, but

which when a seam is passing under it will rise bodily to allow it topass under. This is especially useful in connection with a ma- 2 5 chineof the character described, Where the presser-foot is made in two parts,one part bearing on that portion of the fabric'to be ruffled, while theother bears on the thicknesses of goods not ruffled, for if thepresser-foot has only a tilting motion on its pivot when a heavy seam ora high ridge of cloth is reached the foot will tilt when the projectionstrikes the toe of the foot, but will bind beneath the body of the part.So, also, if the foot has only a vertical bodily-sliding movement whenthe projection strikes the toe there will be a bind,

which will last until such time as the ridge of the goods reaches thecentral point of the foot. By providing, however, an arrangeo ment offeet in which the part bearing on the ridge both tilts and lifts bodilythe foot will first tilt as the ridge or seam strikes and will thengradually rise bodily as the ridge or seam passes under it.

The invention therefore consists of a presser-foot having a part whichboth tilts and has a bodily-vertical movement.

It also consists of a presser-foot having a part which is pivoted to themain part, said part and its pivot being movable up and down.

Finally it consists in the matters hereinafter described, and referredto into the appended claim.

The invention is illustrated in the accompanying drawings, in which-Figure '1 is a perspective view of a portion of a Union Special YokeRuffling Machine, showing myinvention applied thereto. Fig. 2 is aperspective view of the presser-foot. Fig. 3 is a vertical section ofthe presser-foot in a plane including the line 1 1 of Fig. 2. Fig.4 is across-section on line 2 2, Fig. 3.

In the drawings, A represents the bed-plate,

B the gooseneck, C the needle-lever, D the needle-bar, E thepresser-bar, and F as a Whole the mechanism supporting and actuating theruffler-blade, all these parts being similar in construction andoperation to corresponding parts shown and described in the applicationabove referred to.

The presser-foot to which especially the present invention relates isshown with its shank 1 adapted to be clamped around the lower end of thepresser-bar E. It is provided with the integral rigid part 2, adapted tobear on that portion of the fabric which is to be ruffled and united tothe other portions of the fabric. The other portion 3 of the presserfoothas the upwardly-extending lugs 44, embracing the part 5, formed withthe shank of the presser-foot and pivoted thereto by means of thepivot-pin 6. The pivoted portion 3 of the foot is provided with openingsfor the passage of the needles and bears on the portion of the fabricoutside the line of ruffling and by reason of the fact that it ispivoted will tilt when an extra thickness of goods, such as a seam,passes under it. To permit of the part 3 also moving bodily as well astilting for the purpose referred to in a former part of thisspecification, this part 5 where the pivot-pin6 goes through it isvertically slotted, so that as the part 3' is pressed up by the actionof the fabric beneath it the pivotpin will slide in the slot 7 Normallythe part 3 5 is kept pressed down to its work by means of the spring 8,secured to the shank of the foot by the screw 9, the free end of thespring resting upon the cross-bar 10, extending between the lugs 4 4.

walls embracing the rigid vertical part and provided with a pivotpinpassing through said vertical embracing walls and loosely fittint, theslot, with means for keeping said second portion normally depressed uponthe fabric, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
